Hello AFN, I have been lurking around for a few months trying to get a feel for things and trying to pick up some knowledge from the experienced people around here. I am new to growing. This is my very first run. I decided to go with autoflowers due to my personal circumstances. I could use all the help I can get. I am currently running 2 five gallon buckets with 6 inch netpots. Each bucket has 2 medium size air stones being pumped by an eco 1 commercial air pump. Each bucket also has a aquarium water heater set for 69 degrees. Light is a 400w metal halide about 21 inches from the tops of each plant. Also using a 4 inch inline fan and carbon filter for exhaust. My plants are about 4 weeks old on 400 ppm nutes. I use general hydroponics flora series performance pack for nutes drain to waste at about half strength. Also use calimagic, hygrozyme, aqua shield, sm-90 and have some great white myco. I think I may have given nutes a little too late or maybe not enough early on. I feel they may be a little stunted, but then again maybe I'm just overly paranoid lol. The roots have some brown on them but it wipes off and doesn't have a smell. There are also some brown clumps in parts of the root mass. All the new growth however looks pretty good, as in white. I will include some pics. Can anyone help me learn on this exciting journey? Any input is very appreciated. What do the leaves look like what may be wrong, or was wrong? Oh btw, the strains are dinafem white widow auto and sweet seeds sweet cheese auto. If you have any other questions let me know. Thanks!
